Kalshi CEO Cites Nasdaq in $36 Billion New York Lawsuit Defense

Kalshi CEO Tarek Mansour defended the prediction market operator on August 3 after New York filed a lawsuit seeking at least $36 billion in damages, penalties, and related relief. New York alleges Kalshi operates an unlicensed gambling platform, a claim Mansour refutes by comparing Kalshi’s structure to Nasdaq.

What Happened

New York filed a lawsuit against Kalshi on July 31, seeking at least $36 billion in damages, penalties, and related relief, alleging the prediction market firm operates an unlicensed gambling platform (Crypto News). Following the filing, Kalshi removed the proceeding to the U.S. District Court for the Southern District of New York approximately eight hours later (Crypto News).

This removal subsequently led New York Supreme Court Justice Melissa A. Crane to treat the state’s preliminary injunction request as moot, as the case was no longer before her court (Crypto News). This procedural decision did not, however, reject New York’s underlying allegations (Crypto News).

Key Details

• New York’s petition accuses Kalshi of repeatedly violating state gambling laws by offering event contracts without a New York State Gaming Commission license (Crypto News).
• Kalshi CEO Tarek Mansour compared Kalshi’s platform to Nasdaq, stating that both match traders and charge transaction fees (Crypto News).
• The company transferred the case to federal court, arguing that New York was attempting to regulate a derivatives exchange overseen by the Commodity Futures Trading Commission (Crypto News).
• New York’s attorney general’s office alleges the company allows customers to risk money on future events outside their control, fitting New York’s definition of gambling, and claims individuals aged 18 to 20 can use the platform despite a 21-year minimum age for mobile sports betting (Crypto News).
• Kalshi is registered with the CFTC as a designated contract market, which it cites in its defense that event contracts are financial instruments, not wagers (Crypto News).
• A reported $22 billion company valuation and annualized transaction volume of $178 billion were cited in the state filing, though these are reported numbers by the firm and not court findings (Crypto News).

Why It Matters

The lawsuit and Kalshi’s defense highlight a regulatory conflict between state gambling laws and federal oversight of derivatives markets (Crypto News). Kalshi’s argument that its event contracts are financial instruments under CFTC jurisdiction, rather than traditional gambling, challenges the scope of state regulatory authority over such platforms (Crypto News).

This dispute carries broader implications for the event contract business, potentially setting precedents for how federally regulated exchanges operate within state-specific legal frameworks (Crypto News). Mansour suggested that if New York’s legal logic holds, it could also apply to established financial exchanges like Nasdaq, indicating the potential for wider industry impact (PANews English).

What’s Next

The federal judge assigned to New York’s removed case must now determine whether federal jurisdiction exists and whether the proceeding should remain in federal court (Crypto News). A remand would allow New York to renew its injunction request in state court (Crypto News). Keeping the case in federal court would move the immediate dispute into the same court system already handling related questions about CFTC authority and federal preemption (Crypto News).
